Notes. The reported uncertainty for each chemical species in column 2 is: . The Solar reference abundances are from Asplund et al. (2005) for light elements and Grevesse et al. (2015) for heavy elements. ( † )The BACCHUS pipeline was used to derive the broadening parameters, metallicity, and chemical abundances.
